== | == Sensors with analog current output == | ||
There are no special current inputs in the Wiren Board NETMON-1, but you can use a resistor 100-300om, convert the current into voltage and connect as in the previous paragraph. | |||
=== | ==== Sensors with resistive output ==== | ||
Using an external resistor and a reference voltage, the divider must be assembled to obtain a voltage output (see previous paragraphs). | |||
As a reference you can use the output of +5V from pins 7-8 of connector A1, 1 to 2 of the connector I2. | |||
The sensors are conveniently connected to the "A1" connector, which has two ADC inputs and reference voltages. | |||
=== | === Analog sensors with external power supply === | ||
Analog sensors with external power, such as electrochemical sensors series MQ-xxx, humidity sensors HIH-4000, etc. It is also convenient to connect to the connector "A1", which has ADC inputs and reference voltages. | |||
== | == Sensors/counters with pulse outputs == | ||
Such devices form a signal by closing two wires that are suitable for them. | |||
Connect one wire to the "Isolated GND" pin. | |||
Connect the second wire to one of the corresponding contacts (discrete input) of connectors I1,I3,i5,i7,I9. | |||
Some counters have a pulse output on the optocoupler, then the two wires have a polarity - "plus" and "minus". | |||
In this case, the minus is connected to "Isolated GND", "plus" to "discrete input". | |||
=== | === Network connection of 1-Wire === | ||
The 1-wire connection uses the I2 connector. | |||
Connect the ground of the network to the contacts GND (7-8@I2, etc.) or common ground bus. | |||
Data line to "1-Wire" contact ( 4@I2). | |||
Power line to contact "5V" (1-2@I2) (internal power supply). | |||
External 1-Wire bus power supplies are allowed. | |||
When using a passive power supply pin of each sensor is connected to the earth wire. | |||
In this case, the bus consists two wires attached, respectively, to '1-Wire "and" GND ". | |||
=== | === RS-485 network connection === | ||
See [[RS-485/en|RS-485]]. | |||
The Wiren Board NETMON-1 has two RS-485 ports on the "I6" and "I8" connectors. | |||
Lines A B are connected to terminals A and B respectively. | |||
== | == Temperature and humidity sensor == | ||
Wiren Board NETMON-1 | Wiren Board NETMON-1 can be equipped with a built-in temperature and humidity sensor. For more information, see [[Sensor SHT1x/en|SHT1x Sensor]]. | ||
